    Problem in seam-gen reverse engineered database

    David Binder Newbie

      Hello,

      I'm new to jboss-seam and I wanted to demonstrate the power of seam and seam-gen to my co-workers and bosses. I tried reverse engineer a recent application we developped to show the time that should have been spared. but ...
      I ended up with exceptions (always of the same kind)

      the exceptions seems to take place on relationship tables (thoses things you should simply not CRUD). I admit that the side of the application should be deleted in a real-life project but as I said it's for framework testing purpose;

      here are the exception and incriminated beans and jsf.

      JSF:

      <s:link view="/CUtiliserOrList.xhtml"
       value="CUtiliserOr List"
       propagation="none"/>
      


      exception:
      javax.faces.el.PropertyNotFoundException: Bean: entity.CUtiliserOrList_$$_javassist_259, property: cUtiliserOr
